I've been using a dummy smtp server called DevNull SMTP so that I can test my app which sends out notification emails. It has a nice simple GUI, very helpful, but can't be scripted easily. I can't even start it listening to port 25. I have to run the app and then click on the start button...

Is there a similar app that can be scripted easily? Scripted in the sense that I can control it from a bash script or w开发者_运维问答indows batch file and possibly even query the emails from my unit/functional tests.

there is a nice trick with python: http://muffinresearch.co.uk/archives/2010/10/15/fake-smtp-server-with-python/

Just one liner can do the job (listens on port 2500):

python -m smtpd -n -c DebuggingServer localhost:2500

Disclaimer - I work for the company behind this service linked to below.

You can also use a hosted email testing service like Mailosaur. Some of them (ours included) come with an API for integrating into your tests.

That way if you hit a problem you've got someone else to do the hard work in adding new features, etc. for you.

I had a similar problem. Since I stumbled during my research over this question, here is what I ended up with:

For unit testing you can use subethasmtp. Base on subethasmtp I also wrote a program that you can use to call from scripts an query the results: developmentSMTP
